You should be fine. A wood siding, egress windows, cement floor, probably a rectangular box with prefect right angles. Nothing too complex. Have a professional look at your walls to make sure there aren't any structural issues. Have a carpenter deal with the egress windows. Look into tile or linoleum for the flooring. Tile is very nice for basements if you can do it yourself. Sheet vinyl (linoleum) has come a long way and is much cheaper and easier to install. Do what you feel comfortable doing and sub out the rest. I think you'll be able to handle it and will be happy with the results.
